This study was conducted to detect the prevalence of Metallo-Beta-Lactamases (MBLs) and Extended Spectrum Beta-Lactamases (ESBLs) in bacterial isolates from clinical community settings two communities Delta State, Nigeria. Eighty four obtained blood, urine, wound stool patients subjects were analyzed identified by standard microbiological methods. Carbapenemase detection carried out using modif...

EDITOR,—Doubling of the optic disc is rare and can manifest as true or pseudo doubling. A 64 year old man was referred by his physician who noted “a clear area between each optic disc on both sides” during a routine check. Visual acuities and anterior segments were normal. Funduscopy revealed an appearance simulating double optic discs on each side. The right eye showed a 2 disc diameter (DD) s...

We investigated the tissue-specific effects of dichlorodyphenyltrichloroethane (DDT) isomers in adult and suckling newborn mice, using a novel mouse line engineered to express a reporter of estrogen receptor transcriptional activity (ERE-tkLUC mouse). The DDT isomers p,p'-DDT [1,1,1-trichloro2,2-bis(p-chlorophenyl) ethane] and o,p'-DDT [1,1,1-trichloro-2(p-chlorophenyl)-2-(o-chlorophenyl) ethan...

The cutter spacing relate to the rock breaking efficiency of TBM. double disc cutters rolling marble model is established by using ABAQUS based on principle specific energy calculation. effect amount analyzed, and in different calculated. simulation results show that geological conditions marble, when penetration 6mm, 78mm smallest. broken experiment was carried out comprehensive test bench. wi...

Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold (PC50, 1.67 × 10(-6) ...

BACKGROUND Although dichlorodiphenyl trichloroethane (DDT) exposure is known to affect human endocrine function, few previous studies have investigated the effects of DDT exposure on age at menarche or menstrual cycle length. METHODS A cross sectional study was conducted to study the effects of DDT exposure on age at menarche and menstrual cycle length among 466 newly married, nulliparous fem...

We previously demonstrated a good correlation between the increased relative liver weight caused by DDT and the area under the concentration-time curve (AUC) of DDT or the total DDT (T-DDT) in plasma and liver of rats in a 7-day repeated dose study at 1000 ppm. To confirm the reliability of AUC for predicting toxic responses at different dose levels, we conducted a further 28-day repeated dose ...
